Go to ESPN on the internet, click on soccer and then read every article that comes up about the EPL. It is easier than you would think as there are only about six teams that really matter; the rest are decoration.
So you have to know about Manchester United, how they had a great trainer who retired two years ago, Sir Alex Ferguson, and how the current trainer, a despicable human being named Van Gall (pronounced Hall) has brought them back a bit. Wayne Rooney remains the star and key player.
You have to know that Chelsea likes blue and that its trainer, Jose Mourinho, is a megalomaniac and soccer genius, who wins at all costs. He makes radical personnel moves, dumping great players and ignoring players with high salaries if he thinks they are not effective. Former Spanish stars Cesc Fabregas, Diego Costa, and goalie Courtois are the backbone of the squad.
You have to know that Arsenal has a trainer with the same name, Arsene, who always does a great job of getting a team that starts slowly to finish in the top four. Her seems to prefer players from the continent. Of the six French players on the roster, FW Olivier Giroux is at his professional peak.
You have to know that Liverpool is the most emotion-driven team with the “you’ll never walk alone” mentality and the annual observance of one of the terrible soccer tragedies, the Hillsborough disaster where almost 100 fans were crushed to death. The team has the most talented group of strikers, Balotelli, Sturridge, and Sterling, but none have lived up to the level of the biter, Luis Suarez, who transferred to Barcelona during the summer.
Finally, there is the other team from Manchester, City, that has used the stability of a great defense led by Vincent Kompany, to win championships in recent years. An aging team, it might be in decline at the present moment.
Tottenham has the emerging star Harry Kane and is one the verge of greatness, which will only happen if it can hang onto its emerging stars like Kane, Yedlin, and Ericson.
Other than these six teams, most of the rest are either fighting to avoid relegation or to finish in the top six.
PS. Use wikipedia. There is almost no better source for roster, history, and inside information than this wonderful source.
